Answer:
f
−
1
(
x
)
=
1
2
x
+
5
Explanation:
f
(
x
)
=
2
x
−
10
→
Replace the
f
(
x
)
with
y
y
=
2
x
−
10
→
Switch the places of the x and the y
x
=
2
y
−
10
→
Solve for y
x
+
10
=
2
y
y
=
1
2
x
+
5
The inverse is
f
−
1
(
x
)
=
1
2
x
+
5
Your answer is 4 and 8.
What I did was look at numbers that added up to 12 (1,11, 2,10, 3,9) and then find a pair that could be multiplied together and get 32. Have a nice day!!!
By using x-method we got that factorization is (x+5)(x-5)
<h3>What is factorization ?</h3>
factorization is writing a expression as a product of several factors.
So Given polynomial is
Now we will factorise this using x method
Here a=1 b=0 and c= -25
so ac=-25
Now We will write -25 at the top.
and 0 at the bottom.
No we will find two numbers that multiply to the top number -25 and add to the bottom number 0. Hence those numbers are -5 and 5.
Now we can write equation as
By using x-method we got that factorization is (x+5)(x-5)

I think answer should be e. Please give me brainlest let me know if it’s correct or not okay thanks bye I appreciate it
5 + w = 5^2
5 + w = 25
w = 25 -5
w = 20 :)))
i hope this is helpful
have a nice day
